SECTION 2
INSTALLATION
GENERAL – On receipt of the unit, check for any dam-
age that may have occurred during transit or handling.
Report any damage or missing parts as soon as pos-
sible.
Do not electric weld on the compres-
sor or base; bearings can be damaged
by passage of current.
LIFTING UNIT – Proper lifting and/or transporting
methods must be used to prevent damage. Lifting slots
are provided in the base for towmotor use. The unit may
also be moved into location by rolling on bars.
Lift compressor unit by base only. Do
not use other places such as motor,
compressor or discharge manifold
piping as lifting points.
The eyebolts or lugs provided on the
motor are for lifting the motor only
and should not be used to lift any
additional weight. All eyebolts must
be securely tightened. When lifting
the motor the lifting angle must not
exceed 15 degrees. Failure to observe
this warning may result in damage to
equipment or personal injury.
LOCATION – The compressor should be installed, in
a clean, well–lighted, well–ventilated area with ample
space all around the unit for maintenance. Select a
location that provides a cool, clean, dry source of air.
In some cases it may be necessary to install the air filter
at some distance from the compressor to obtain proper
air supply.
Do not install this compressor in a
location that may be subject to tem-
peratures below 32
_
F. (0
_
C.).
Below freezing temperatures will
cause damage to the compressor.
Both the air–cooled and water–cooled units require
cooling air as well as air to the compressor inlet. Proper
ventilation MUST be provided; hot air must be ex-
hausted from the compressor operating area. A typical
inlet–outlet air flow arrangement is shown in
FIGURE 2–1.
Air–Cooled Units – A combination water/aftercooler
is supplied as standard equipment on all air–cooled
units. The air–cooled motor and fan are mounted to the
